Application May 19, 1939, Serial No. 2743193 My invention relates to window supporting mechanism and particularlytosupporting means for a window which permits the window to be raised and loweredfrom and into thewell by mechanism supported wholly within the well.

In the copending application of Alfred H. Haberstump, Serial No. 245,575, filed December 14, 1938, now .Patent No. 2,246,249, datedJun'e 17,1941, and assignedto the assignee of the present invention, amechanism was disclosed and claimed which was attached to projecting legs on a window frame which operated in chan nels one of which was spring pressed. A V- shaped groove was provided in the channel and wheels on the legs'were bevelled to fit the groove to provide support against tilting both in the planeof the glass and laterally thereof. i,

The present invention is a modificationof the invention of the application above mentioned, wherein the construction is simplified while maintaining the same or increasing the rigidity of-the window when, in raised position. -In the present construction, the Wheels are mounted on an element having sufiicient length, to space the wheels 2, material distance apart and a slot is provided in the element medially. of the wheels by which the element'is secured to the legs of the window frame. A pin supports the element for tilting movement as well as movement toward and away from the'guide channel. Springs are provided on the back of the element adjacent to the wheels for urging the element and wheels bodily outwardly toward the guide channel,

The guide channels are rigidly mounted and the springs on the carriage are depended upon to retain the wheels in contact. with the notch in the channels whilepermitting the tilting of the wheel supporting element or its bodily movement toward and from the notch. 'On the front 'door. and onsome rear doors, the channels are mounted at the side edges of the well to have the legs move upwardly. and downwardly therein. In certain rear doors having a cutaway portion, one. channel is disposed out of the plane of the window .and inwardly of the edge within the well and the wheel supporting element is mounted to align with the channel to have the wheels thereof operate within the channel notches to function in the same manner as the wheels function in the channel at the end of the wellin the plane of the window.

At the side of the door panel, additional trackways are provided, of inwardly presented channel formation in which rollers mounted on the side of 'thenwindow supporting mechanism 7 thereby decreases the amount 2Claims. (01. 296-445) i 1 Q I.

engage. Eachfof the rollersis'mouned on an independently hinged :suppo'rt having a spring associated with the end epposite'to' that which is pivoted to force" the rollers'outwardly of the support into the "guides. The-additional ,sid'e supports for the window resists the movement of the window normal to itsplane when in raised position 'lfhe trackways may slope away from the plane of the windowtoward'the bottom to decrease the spring pressure on the rollers "which e of effort frequired to operate the window mechanism.

hAoeoidihgjly, the main objects of my inven tion are: to siipporta window byfwhe'els on a tiltable element operating in channels which'a're rigidly mounted within the 'well ofi'a door or vehicle body; to provide awi'ndow having rollers on" the ends engagingend tr'ackways with spaced rollers on the side which engage spacedtrackways within the window well'dispo's'edout ofthe plane of the window; to provide an elementwith space rollers having bevelled. edges which are spring pressed outwardlyfin. afv' groove channel; to mount an elementhaving rollers'for pivotal and bodily movement when urged by springs disposed on opposite sides of a supporting pivot; to provide a bracket for reinforcing the edge of a window in which an elementv is mountedfor pivotal and bodily movement when urged bysprihgsdisposedion opposite sides of a supporting pivot to force the Wheels of the element against a V-notch in a guide rail which is rigidly mounted within a window well; and in general, to provide means for supporting a window which issimplein construction, positive in operation, and economical of manufacture.

Referring to Figs. 6, 7, and 8, I have shown a further modified form of my invention, wherein a casting 31 has a projecting end 38 for strengthening the corner of the window and for providing a support for the element I6. The castin forms abracket hayin an outwardlypresen edchannel ti wte 'itt si tm .i i el .f bodily and tilting movement by a pin 4'] which is press fitted into the casting.

This provides a sup- 7 port for the edge of the window within the Well when the lower corner thereof is'obstructed in such manner as to prohibit the use of the rail at that point.

The spring pressed rollers on the lower cross member of the window frame provide a resistance-to a movement normal to the plane of the .1. window, especially in its completely raised posi-' tion(, The guideways for the rollers may slope away from the plane of the window medially of their length to decrease the spring tension provided therebetween as the Window is lowered while providing a maximum tension when the window is near its raised position.

combination, an inverted U-shaped frame encompassing a window pane, the ends of which tilting and bodily movement-toward and from the webs thereof, bevelled wheels pivoted near the ends of said elements in a' position to pro ject through the apertures of said webs, spring supporting members, bracing members, and
